Blanking Time (3-Level)

Purpose

Generate commutation delay for 3-level inverter bridges

Library

Control / Modulators

Description

This block generates a blanking time for 3-level inverter bridges so that the turn-on of one switch is delayed with respect to the turn-off of the other switch in the same inverter leg.

The input s is a switching function with the values \(-1\), \(0\) and \(1\) generated by a 3-level modulator such as the Symmetrical PWM (3-Level). The values of the output s’ are either \(-1\), \(-0.5\), \(0\), \(0.5\) or \(1\). If the input is a vector, the output is also a vector of the same width.

Parameters

Delay time

The delay in seconds \((\mathrm{s})\) between the turn-off of one switch and the turn-on of another switch in an inverter leg.
